Direct numerical simulations are extended to see the effects of time-periodic blowing frequency from a spanwise slot on a turbulent boundary layer. The time-periodic blowing frequency is given in a range 0≤f≤0.08 at a fixed blowing amplitude of A=0.5. The effects of the blowing frequency are scrutinized by examining the phaseor time-averaged turbulent statistics. A most effective blowing freque...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

Atomic-scale calculations indicate that both stress effects and chemical binding contribute to the redistribution of solute in presence vacancy clusters magnesium alloys, leading segregation driven by thermodynamics. As size cluster increases, becomes more important relative stress. These solute–vacancy interactions also impact diffusivity vacancies a solid solution. Simulations show atoms acce...

Breakdown is one of main failure mechanisms that limit write endurance ferroelectric devices using hafnium oxide-based materials. In this study, we investigate the gate current and breakdown characteristics Hf0.5Zr0.5O2/Si field-effect transistors (FeFETs) by carrier separation measurements to analyze electron hole leakage currents during time-dependent dielectric (TDDB) tests. Rapidly increasi...

Gastrointestinal epithelium faces osmotic stress, both at physiological and pathophysiological conditions. JNK activation is an immediate cellular response to osmotic stress. We investigated the effect of osmotic stress on intestinal epithelial barrier function and delineated the role of JNK2 in osmotic stress-induced tight junction (TJ) regulation in Caco-2 cell monolayers and ileum of Jnk(-/-...

Abstract The slowdown of pressure solution creep has been thought to be caused by stress redistribution. This study presents a fresh view towards this behaviour. Basically, two rate-limiting mechanisms come into play amid creep: (1) redistribution across expanding inter-granular contacts and (2) solute accumulation in the water film. Because non-hydrostatic dissolution occurs under open system ...
